The premium solution for wettability analysis of microscopically small surfaces
The wettability of very small surfaces can have a great influence on product quality, e.g. for contact points on circuit boards or in microfluidics. The DSA100M Drop Shape Analyzer is the premium solution for accurately positioning and analyzing drops in the picoliter range. The resulting contact angle is exactly the information you need for optimizing wetting and coating processes on very small surfaces.
